Systems and methods for saw tooth milling to prevent chip fraud

ABSTRACT

Example embodiments of systems and methods for milling patterns for a card are provided. A chip fraud prevention system include a device including a chip. The chip may be at least partially encompassed in a chip pocket. The chip pocket may include one or more shapes. The one or more shapes may include one or more peaks and one or more valleys. One or more connections may be communicatively coupled to at least one surface of the chip. The one or more connections may be placed between at least one of the one or more peaks or one or more valleys.

FIELD OF THE INVENTION

The present disclosure relates to systems and methods for milling patterns for a card, such as a smartcard, and more particularly, to systems and methods for saw tooth milling to prevent chip fraud.

BACKGROUND

Removing a chip from one smartcard and inserting it into another smartcard or other device increases the risk of fraud. Moreover, conventional chip placement methods, such as methods that use smooth milling patterns, are ineffective due to the ease of chip removal. For example, for smartcards having chips, there is a significant likelihood of the removal of chips that are not securely positioned, such as by physical removal or thermal removal, and these chips may then be subject to re-implantation into another card or other device. As a consequence, smartcards having chips may be fraudulently manipulated, reprogrammed, and/or otherwise misused.

These and other deficiencies exist. Accordingly, there is a need for a chip fraud prevention system that improves security, reduces the risk of fraud, reduces cost, and increases durability.

SUMMARY

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

Systems and methods described herein are directed to improving durability for chip placement methods in a contactless card, including saw tooth milling pattern and other means of preventing removal of the chip described herein. As further described below, the saw tooth milling pattern promotes the success of adhesion of the chip to a chip pocket of the contactless card while also creating an uneven cutting process to prevent removal of the chip. As a consequence of this and the other removal prevention designs described herein, chip fraud is reduced or eliminated. Further cost and resource savings may be achieved through a decrease in fraud, including decreased needs for investigating and refunding fraudulent transactions, customer support, and replacing smartcards.

FIG. 1A illustrates one or more contactless cards 100, which may comprise a payment card, such as a credit card, debit card, or gift card, issued by a service provider 105 displayed on the front or back of the card 100. In some examples, the contactless card 100 is not related to a payment card, and may comprise, without limitation, an identification card, a membership card, a data storage card, or other type of card. In some examples, the payment card may comprise a contactless card, such as a dual interface contactless payment card, a contact card that requires physical contact with a card reader, or other type of chip-based card. The card 100 may comprise a substrate 101, which may include a single layer or one or more laminated layers composed of plastics, metals, and other materials. Exemplary substrate materials include polyvinyl chloride, polyvinyl chloride acetate, acrylonitrile butadiene styrene, polycarbonate, polyesters, anodized titanium, palladium, gold, carbon, paper, and biodegradable materials. In some examples, the card 100 may have physical characteristics compliant with the ID-1 format of the ISO/IEC 7810 standard, and the card may otherwise be compliant with the ISO/IEC 14443 standard. However, it is understood that the card 100 according to the present disclosure may have different characteristics, and the present disclosure does not require a card to be implemented in a payment card.

The card 100 may comprise account number information 110 that may be displayed on the front and/or back of the card 100. The card 100 may also include identification information 115 displayed on the front and/or back of the card 100, and a contact pad 120. In some examples, identification information 115 may comprise one or more of cardholder name and expiration date of the card 100. The contact pad 120 may be configured to establish contact with another communication device, such as a user device, smart phone, laptop, desktop, or tablet computer. The card 100 may also include processing circuitry, antenna and other components not shown in FIG. 1A. These components may be located behind the contact pad 120 or elsewhere on the substrate 101. The card 100 may also include a magnetic strip or tape, which may be located on the back of the card (not shown in FIG. 1A).

As illustrated in FIG. 1B, the contact pad 120 of FIG. 1A may include processing circuitry 125 for storing and processing information, including a microprocessor 130 and a memory 135. It is understood that the processing circuitry 125 may contain additional components, including processors, memories, error and parity/CRC checkers, data encoders, anticollision algorithms, controllers, command decoders, security primitives and tamperproofing hardware, as necessary to perform the functions described herein.

The memory 135 may be a read-only memory, write-once read-multiple memory or read/write memory, e.g., RAM, ROM, and EEPROM, and the card 100 may include one or more of these memories. A read-only memory may be factory programmable as read-only or one-time programmable. One-time programmability provides the opportunity to write once then read many times. A write once/read-multiple memory may be programmed at a point in time after the memory chip has left the factory. Once the memory is programmed, it may not be rewritten, but it may be read many times. A read/write memory may be programmed and re-programmed many times after leaving the factory. It may also be read many times.

The memory 135 may be configured to store one or more applets 140, one or more counters 145, and a customer identifier 150. The one or more applets 140 may comprise one or more software applications configured to execute on one or more cards, such as Java Card applet. However, it is understood that applets 140 are not limited to Java Card applets, and instead may be any software application operable on cards or other devices having limited memory. The one or more counters 145 may comprise a numeric counter sufficient to store an integer. The customer identifier 150 may comprise a unique alphanumeric identifier assigned to a user of the card 100, and the identifier may distinguish the user of the card from other card users. In some examples, the customer identifier 150 may identify both a customer and an account assigned to that customer and may further identify the card associated with the customer's account.

The processor and memory elements of the foregoing exemplary embodiments are described with reference to the contact pad, but the present disclosure is not limited thereto. It is understood that these elements may be implemented outside of the pad 120 or entirely separate from it, or as further elements in addition to processor 130 and memory 135 elements located within the contact pad 120.

In some examples, the card 100 may comprise one or more antennas 155. The one or more antennas 155 may be placed within the card 100 and around the processing circuitry 125 of the contact pad 120. For example, the one or more antennas 155 may be integral with the processing circuitry 125 and the one or more antennas 155 may be used with an external booster coil. As another example, the one or more antennas 155 may be external to the contact pad 120 and the processing circuitry 125.

In an embodiment, the coil of card 100 may act as the secondary of an air core transformer. The terminal may communicate with the card 100 by cutting power or amplitude modulation. The card 100 may infer the data transmitted from the terminal using the gaps in the card's power connection, which may be functionally maintained through one or more capacitors. The card 100 may communicate back by switching a load on the card's coil or load modulation. Load modulation may be detected in the terminal's coil through interference.

As illustrated in FIG. 2A, system 200 depicts various schematics of a surface of a contact pad and a chip. FIG. 2A may reference the same or similar components as illustrated in FIG. 1A and FIG. 1B, including the card, chip and the contact pad. In some examples, the chip may comprise an integrated circuit. In one example, contact pad 205 may include a planar surface 210 comprising a pad substrate 215 and a chip 220 embedded, integrated, or otherwise in communication with contact pad 205 via one or more electronic components or connections 225. For example, one or more connections 225 may comprise one or more leads, wires or pins, or any combination thereof, communicatively coupled to chip 220. One or more connections 225 may be configured to connect to a chip surface 230 of the chip 220. As illustrated in FIG. 2A, the chip surface 230 may comprise an exterior region of chip 220, and the chip 220 is shown as projecting outwards from card 205 to depict its connectivity.

As illustrated in FIG. 2B, the one or more connections 225, as previously depicted in FIG. 2A, are shown as being removed. FIG. 2B may reference the same or similar components of contact pad 205 as previously described with reference to FIG. 2A. In some examples, removal of the one or more connections 225 may take place by one or more structures 265, including but not limited to one or more of wire cutters, scissors, clippers, picks, pliers, pins, threads, needles, blades, knives, or any other structure, or any combination thereof, configured to remove the one or more connections 225.

As illustrated in FIG. 2C, the one or more connections 225, as previously depicted in FIG. 2B, have been severed due to the removal by one or more structures 265 as explained above with reference to FIG. 2B. FIG. 2C may reference the same or similar components of card 205 as previously described with reference to FIG. 2B.

FIG. 2D illustrates another example of a contact pad and a chip. As shown in FIG. 2D, contact pad 235 includes a planar surface 240 comprising a pad substrate 245 and a chip 250 embedded, integrated, or otherwise in communication with card 205 via one or more electronic components or connections 255. For example, one or more connections 255 may comprise one or more wires or pins, or any combination thereof, communicatively coupled to chip 250. One or more connections 255 may be configured to connect a surface 260 of the chip 250. As illustrated in FIG. 2D, surface 260 may comprise an interior region of chip 250, and the chip 250 is shown as projecting outwards from card 205 to depict its connectivity. As further illustrated in FIG. 2D, one or more connections 255 of card 235 have not yet been severed.

As illustrated in FIG. 2E, the one or more connections 255 of card 235, as previously depicted in FIG. 2D, are shown as being removed. FIG. 2E may reference the same or similar components of card 235 as previously described with reference to FIG. 2D. In some examples, removal of the one or more leads 255 may take place by one or more structures 265, including but not limited to one or more of wire cutters, scissors, clippers, picks, pliers, pins, threads, needles, blades, knives, or any other structure, or any combination thereof, configured to remove one or more connections 255.

As illustrated in FIG. 2F, the one or more connections 255 of card 235, as previously depicted in FIG. 2E, have been severed due to the removal by one or more structures 265 as explained above with reference to FIG. 2E. FIG. 2F may reference the same or similar components of card 235 as previously described with reference to FIG. 2E.

As illustrated in FIG. 3A, system 300 depicts a schematic of cross-sectional view of a chip pocket of a card. FIG. 3A may reference the same or similar components as illustrated in FIGS. 2A-2F, such as a card, one or more connections, and a chip. Card 305 may comprise a chip 310 that is at least partially or wholly positioned on or at least partially or wholly encompassed or at least partially or wholly integrated within a housing or reservoir, the housing or reservoir comprising a chip pocket 315. In some examples, the one or more peaks and one or more valleys 320 may comprise one or more air gaps. In some examples, the one or more peaks and one or more valleys 320 may comprise one or more tapered or jagged edges. Although single instances of the chip 310 are depicted in FIG. 3A, one or more chips 310 of card 305 may be at least partially or wholly positioned on or at least partially or wholly encompassed or at least partially or wholly integrated within one or more housings or reservoirs.

In some examples, the one or more peaks and one or more valleys 320 of the chip pocket 315 may be generated or designed via a saw tooth milling pattern. The saw tooth milling pattern may be programmed or machined by a machine (not shown). In contrast to a smooth milling pattern, the saw tooth milling pattern for the chip pocket 315 or a derivation of the saw tooth milling pattern, makes it difficult to attempt removal and/or remove the chip 310 from the card 305. Thus, the saw tooth milling pattern promotes the success of adhesion of the chip 310 to the chip pocket 315 while also creating an uneven cutting process to prevent removal of the chip 310. In addition, one or more adhesives may be applied within the air gaps between the one or more peaks and one or more valleys 320 (e.g., to completely or partially fill the air gaps), which may strengthen the adhesion of the chip 310 within the chip pocket 315. As a consequence of this removal prevention design, removal of the chip may be more difficult and chip fraud may be reduced.

In some examples, each of the one or more peaks and one or more valleys 320 of the chip pocket 315 may comprise same or different shapes, lengths, and/or dimensions so as to produce one or more arrangements of the one or more shapes. For example, although seven types of peaks and valleys are illustrated in FIG. 3A, fewer or greater peaks and valleys may be included, and other types of peaks and valleys 320 may comprise one or more angled and/or curved portions. Accordingly, one or more peaks and one or more valleys 320 may comprise different or irregular shapes, lengths, and/or dimensions. In some examples, one or more subsets of the one or more peaks and the one or more valleys 320 may be generated or repeated after a predetermined interval, or one or more subsets of the one or more peaks and one or more valleys 320 may generated or repeated at random, as determined by one or more machining processes. Although FIG. 3A depicts the card 305, chip 310, one or more connections 320, and one or more peaks and one or more valleys 320, different variations may be used within a given card 305 issuance, such that the same card issued by an institution may have a number of different patterns based on the particular card 305 that is prepared for the user. In the event the user misplaces their card 305, a new card may be issued with an entirely different pattern to replace the previous card.

FIG. 3B illustrates another example embodiment of the system 300 shown in FIG. 3A, including a card 305, a chip 310, a chip pocket 315, and one or more peaks and one or more valleys 320 that may comprise one or more air gaps. As shown in FIG. 3B, one or more connections 325, which may comprise one or more leads, wires or pins, or any combination thereof, may be communicatively coupled to at least a portion of the chip 310. The one or more connection 325 may be disposed between the one or peaks and one or more valleys 320. In some examples, the one or more connections 325 may be disposed within air gaps between the one or peaks and one or more valleys 320. In other examples, the one or more connections 325 may be disposed within the adhesive that may completely or partially fill the air gaps. In either case, if any of the one or more connections 325 are severed during an attempt to remove the chip 310, the chip 310 may not properly function. Accordingly, disposing the one or more leads between the one or peaks and one or more valleys 320 may increase the difficulty of removing the chip and reduce the likelihood that chip fraud may be committed.

As illustrated in FIG. 3C, system 300 depicts a schematic of cross-sectional view of a chip pocket of a card. FIG. 3C may reference the same or similar components as illustrated in FIGS. 3A-3B, such as a card, one or more connections, and a chip. Card 305 may comprise a chip 310 that is at least partially or wholly positioned on or at least partially or wholly encompassed or at least partially or wholly integrated within a housing or reservoir, the housing or reservoir comprising a chip pocket 315. In some examples, the one or more peaks and one or more valleys 320 may comprise one or more air gaps. In some examples, the one or more peaks and one or more valleys 320 may comprise one or more tapered or jagged edges. Although single instances of the chip 310 are depicted in FIG. 3C, one or more chips 310 of card 305 may be at least partially or wholly positioned on or at least partially or wholly encompassed or at least partially or wholly integrated within one or more housings or reservoirs.

In some examples, the one or more peaks and one or more valleys 320 of the chip pocket 315 may be generated or designed via a saw tooth milling pattern. The saw tooth milling pattern may be programmed or machined by a machine (not shown). In contrast to a smooth milling pattern, the saw tooth milling pattern for the chip pocket 315 or a derivation of the saw tooth milling pattern, makes it difficult to attempt removal and/or remove the chip 310 from the card 305. Thus, the saw tooth milling pattern promotes the success of adhesion of the chip 310 to the chip pocket 315 while also creating an uneven cutting process to prevent removal of the chip 310. In addition, one or more adhesives may be applied within the air gaps between the one or more peaks and one or more valleys 320 (e.g., to completely or partially fill the air gaps), which may strengthen the adhesion of the chip 310 within the chip pocket 315. As a consequence of this removal prevention design, removal of the chip may be more difficult and chip fraud may be reduced.

In some examples, each of the one or more peaks and one or more valleys 320 of the chip pocket 315 may comprise same or different shapes, lengths, and/or dimensions so as to produce one or more arrangements of the one or more shapes. For example, although three peaks and four valleys are illustrated in FIG. 3C, fewer or greater peaks and valleys may be included, and other types of peaks and valleys 320 may comprise one or more angled and/or curved portions. Accordingly, one or more peaks and one or more valleys 320 may comprise different or irregular shapes, lengths, and/or dimensions. In some examples, one or more subsets of the one or more peaks and the one or more valleys 320 may be generated or repeated after a predetermined interval, or one or more subsets of the one or more peaks and one or more valleys 320 may generated or repeated at random, as determined by one or more machining processes. Although FIG. 3C depicts the card 305, chip 310, one or more connections 320, and one or more peaks and one or more valleys 320, different variations may be used within a given card 305 issuance, such that the same card issued by an institution may have a number of different patterns based on the particular card 305 that is prepared for the user. In the event the user misplaces their card 305, a new card may be issued with an entirely different pattern to replace the previous card.

FIG. 3D illustrates another example embodiment of the system 300 shown in FIG. 3C, including a card 305, a chip 310, a chip pocket 315, and one or more peaks and one or more valleys 320 that may comprise one or more air gaps. As shown in FIG. 3D, one or more connections 325, which may comprise one or more leads, wires or pins, or any combination thereof, may be communicatively coupled to at least a portion of the chip 310. The one or more connection 325 may be disposed between the one or peaks and one or more valleys 320. In some examples, the one or more connections 325 may be disposed within air gaps between the one or peaks and one or more valleys 320. In other examples, the one or more connections 325 may be disposed within the adhesive that may completely or partially fill the air gaps. In either case, if any of the one or more connections 325 are severed during an attempt to remove the chip 310, the chip 310 may not properly function. Accordingly, disposing the one or more leads between the one or peaks and one or more valleys 320 may increase the difficulty of removing the chip and reduce the likelihood that chip fraud may be committed.

As illustrated in FIG. 3E, system 300 depicts a schematic of cross-sectional view of a chip pocket of a card. FIG. 3E may reference the same or similar components as illustrated in FIGS. 3A-3D, such as a card, one or more connections, and a chip. Card 305 may comprise a chip 310 that is at least partially or wholly positioned on or at least partially or wholly encompassed or at least partially or wholly integrated within a housing or reservoir, the housing or reservoir comprising a chip pocket 315. In some examples, the one or more peaks and one or more valleys 320 may comprise one or more air gaps. In some examples, the one or more peaks and one or more valleys 320 may comprise one or more tapered or jagged edges. Although single instances of the chip 310 are depicted in FIG. 3E, one or more chips 310 of card 305 may be at least partially or wholly positioned on or at least partially or wholly encompassed or at least partially or wholly integrated within one or more housings or reservoirs.

In some examples, the one or more peaks and one or more valleys 320 of the chip pocket 315 may be generated or designed via a saw tooth milling pattern. The saw tooth milling pattern may be programmed or machined by a machine (not shown). In contrast to a smooth milling pattern, the saw tooth milling pattern for the chip pocket 315 or a derivation of the saw tooth milling pattern, makes it difficult to attempt removal and/or remove the chip 310 from the card 305. Thus, the saw tooth milling pattern promotes the success of adhesion of the chip 310 to the chip pocket 315 while also creating an uneven cutting process to prevent removal of the chip 310. In addition, one or more adhesives may be applied within the air gaps between the one or more peaks and one or more valleys 320 (e.g., to completely or partially fill the air gaps), which may strengthen the adhesion of the chip 310 within the chip pocket 315. As a consequence of this removal prevention design, removal of the chip may be more difficult and chip fraud may be reduced.

In some examples, each of the one or more peaks and one or more valleys 320 of the chip pocket 315 may comprise same or different shapes, lengths, and/or dimensions so as to produce one or more arrangements of the one or more shapes. For example, although three peaks and four valleys are illustrated in FIG. 3E, fewer or greater peaks and valleys may be included, and other types of peaks and valleys 320 may comprise one or more angled and/or curved portions. Accordingly, one or more peaks and one or more valleys 320 may comprise different or irregular shapes, lengths, and/or dimensions. In some examples, one or more subsets of the one or more peaks and the one or more valleys 320 may be generated or repeated after a predetermined interval, or one or more subsets of the one or more peaks and one or more valleys 320 may generated or repeated at random, as determined by one or more machining processes. Although FIG. 3E depicts the card 305, chip 310, one or more connections 320, and one or more peaks and one or more valleys 320, different variations may be used within a given card 305 issuance, such that the same card issued by an institution may have a number of different patterns based on the particular card 305 that is prepared for the user. In the event the user misplaces their card 305, a new card may be issued with an entirely different pattern to replace the previous card.

FIG. 3F illustrates another example embodiment of the system 300 shown in FIG. 3E, including a card 305, a chip 310, a chip pocket 315, and one or more peaks and one or more valleys 320 that may comprise one or more air gaps. As shown in FIG. 3F, one or more connections 325, which may comprise one or more leads, wires or pins, or any combination thereof, may be communicatively coupled to at least a portion of the chip 310. In some examples, the one or more connections 325 may be disposed within air gaps between the one or peaks and one or more valleys 320. In other examples, the one or more connections 325 may be disposed within the adhesive that may completely or partially fill the air gaps. In either case, if any of the one or more connections 325 are severed during an attempt to remove the chip 310, the chip 310 may not properly function. Accordingly, disposing the one or more leads between the one or peaks and one or more valleys 320 may increase the difficulty of removing the chip and reduce the likelihood that chip fraud may be committed.

As illustrated in FIG. 3G, system 300 depicts a schematic of cross-sectional view of a chip pocket of a card. FIG. 3G may reference the same or similar components as illustrated in FIGS. 3A-3F, such as a card, one or more connections, and a chip. Card 305 may comprise a chip 310 that is at least partially or wholly positioned on or at least partially or wholly encompassed or at least partially or wholly integrated within a housing or reservoir, the housing or reservoir comprising a chip pocket 315. In some examples, the one or more peaks and one or more valleys 320 may comprise one or more air gaps. In some examples, the one or more peaks and one or more valleys 320 may comprise one or more tapered or jagged edges. Although single instances of the chip 310 are depicted in FIG. 3G, one or more chips 310 of card 305 may be at least partially or wholly positioned on or at least partially or wholly encompassed or at least partially or wholly integrated within one or more housings or reservoirs.

In some examples, the one or more peaks and one or more valleys 320 of the chip pocket 315 may be generated or designed via a saw tooth milling pattern. The saw tooth milling pattern may be programmed or machined by a machine (not shown). In contrast to a smooth milling pattern, the saw tooth milling pattern for the chip pocket 315 or a derivation of the saw tooth milling pattern, makes it difficult to attempt removal and/or remove the chip 310 from the card 305. Thus, the saw tooth milling pattern promotes the success of adhesion of the chip 310 to the chip pocket 315 while also creating an uneven cutting process to prevent removal of the chip 310. In addition, one or more adhesives may be applied within the air gaps between the one or more peaks and one or more valleys 320 (e.g., to completely or partially fill the air gaps), which may strengthen the adhesion of the chip 310 within the chip pocket 315. As a consequence of this removal prevention design, removal of the chip may be more difficult and chip fraud may be reduced.

In some examples, each of the one or more peaks and one or more valleys 320 of the chip pocket 315 may comprise same or different shapes, lengths, and/or dimensions so as to produce one or more arrangements of the one or more shapes. For example, although two peaks and three valleys are illustrated in FIG. 3G, fewer or greater peaks and valleys may be included, and other types of peaks and valleys 320 may comprise one or more angled and/or curved portions. Accordingly, one or more peaks and one or more valleys 320 may comprise different or irregular shapes, lengths, and/or dimensions. In some examples, one or more subsets of the one or more peaks and the one or more valleys 320 may be generated or repeated after a predetermined interval, or one or more subsets of the one or more peaks and one or more valleys 320 may generated or repeated at random, as determined by one or more machining processes. Although FIG. 3G depicts the card 305, chip 310, one or more connections 320, and one or more peaks and one or more valleys 320, different variations may be used within a given card 305 issuance, such that the same card issued by an institution may have a number of different patterns based on the particular card 305 that is prepared for the user. In the event the user misplaces their card 305, a new card may be issued with an entirely different pattern to replace the previous card.

FIG. 3H illustrates another example embodiment of the system 300 shown in FIG. 3H, including a card 305, a chip 310, a chip pocket 315, and one or more peaks and one or more valleys 320 that may comprise one or more air gaps. As shown in FIG. 3H, one or more connections 325, which may comprise one or more leads, wires or pins, or any combination thereof, may be communicatively coupled to at least a portion of the chip 310. In some examples, the one or more connections 325 may be disposed within air gaps between the one or peaks and one or more valleys 320. In other examples, the one or more connections 325 may be disposed within the adhesive that may completely or partially fill the air gaps. In either case, if any of the one or more connections 325 are severed during an attempt to remove the chip 310, the chip 310 may not properly function. Accordingly, disposing the one or more connections 325 between the one or peaks and one or more valleys 320 may increase the difficulty of removing the chip and reduce the likelihood that chip fraud may be committed.

FIG. 4 illustrates a method 400 of making a card. FIG. 4 may reference the same or similar components of FIGS. 1-3, as explained above.

At block 410, method may comprise laminating one or more layers together. In some examples, the one or more layers may comprise an outermost or exterior layer which includes a layer that receives paint, ink, or laser treatment. The outermost or exterior layer may comprise the ceiling or top layer of the one or more laminated layers. The outermost or exterior layer may comprise a thin film that receives laser personalization. In some examples, the laser personalization may comprise custom laser personalization.

The one or more layers may further comprise one or more artwork layers positioned below the outermost or exterior layer. For example, the one or more artwork layers may comprise personalized information about the user and/or financial institution that issues the card.

The one or more layers may further comprise one or more metal core layers positioned below the one or more artwork layers.

The one or more layers may comprise one or more magnetic stripe layer positioned below the one or more metal core layers. In some examples, the one or more magnetic stripe layers may comprise the innermost or interior layer of the card.

In some examples, the one or more layers may be arranged in one or more sheets. By way of an example, each sheet may comprise a plurality of cards. In some examples, one or more sheets may comprise 50 or more cards. The one or more sheets may be fed to a laminating press which is configured to laminate the one or more layers together. In some examples, the lamination process may comprise hot lamination or cold lamination. At this point, the card includes the one or more layers, and does not yet include personal information, a signature panel, a hologram, and a chip.

At block 420, a hologram may be placed on the card. In some examples, the hologram may comprise a secure hologram, and the hologram may be placed on an area of the card. In some examples, the hologram may be placed on a secure area of the card that may be checked by a merchant.

At block 430, a signature panel may be placed on the card. In some examples, the signature panel may be heat stamped onto a portion the card. The signature panel may also be checked by a merchant. The signature panel may be placed on a portion of the card, such as the back of the card.

At block 440, the card may be transferred to one or more machines. The one or more machines may comprise a stamping machine and may be configured to mill one or more chip pockets and embed a chip into the card. In some examples, the card may comprise a chip that is at least partially or wholly positioned on or at least partially or wholly encompassed or at least partially or wholly integrated within a housing or reservoir, the housing or reservoir comprising a chip pocket. As further discussed below, one or more connections may communicatively couple at least a portion, such as a surface, of the chip which may be at least partially or wholly disposed on one or more peaks and one or more valleys of the chip pocket. In some examples, the one or more peaks and one or more valleys may comprise one or more air gaps. In some examples, the one or more peaks and one or more valleys may comprise one or more tapered or jagged edges.

In some examples, the one or more peaks and one or more valleys of the chip pocket may be generated or designed via a saw tooth milling pattern. The saw tooth milling pattern may be programmed or machined by a machine. In contrast to a smooth milling pattern, the saw tooth milling pattern for the chip pocket and one or more connections, or a derivation of the saw tooth milling pattern, makes it difficult to attempt removal and/or remove the chip from the card. Thus, the saw tooth milling pattern promotes the success of adhesion of the chip to the chip pocket while also creating an uneven cutting process to prevent removal of the chip. As a consequence of this removal prevention design, chip fraud is eliminated.

In some examples, each of the one or more peaks and one or more valleys of the chip pocket may comprise same or different shapes, lengths, and/or dimensions so as to produce one or more arrangements of the one or more shapes. Accordingly, one or more connections may comprise different or irregular shapes, lengths, and/or dimensions. In some examples, one or more subsets of the one or more peaks and the one or more valleys may be generated or repeated after a predetermined interval, or one or more subsets of the one or more peaks and one or more valleys may generated or repeated at random, as determined by one or more machining processes. For example, one or more peaks and one or more valleys may be included, and other types of peaks and valleys may comprise one or more angled and/or curved portions. Different variations may be used within a given card issuance, such that the same card issued by an institution may have a number of different patterns based on the particular card that is prepared for the user. In the event the user misplaces their card, a new card may be issued with an entirely different pattern to replace the previous card.

In some examples, the chip may comprise an integrated circuit. In one example, card may include a planar surface comprising a substrate, and a chip embedded or integrated or otherwise in communication with card via one or more electronic components or connections. For example, the one or more connections may comprise one or more leads, wires or pins, or any combination thereof, communicatively coupled to chip. One or more connections may be configured to connect a surface of the chip. The surface may comprise an exterior region of chip, and the chip may project outwards from card to depict its connectivity.

In another example, the card may include a chip embedded or integrated or otherwise in communication with card via one or more electronic components or connections. For example, one or more connections may comprise one or more wires or pins, or any combination thereof, communicatively coupled to chip. One or more connections may be configured to connect a surface of the chip. The surface may comprise an interior region of chip, and the chip may be project outwards from the card to depict its connectivity.

At block 450, after the one or more chip pockets are created for housing the chip, the one or more machines may be configured to punch the chip into the one or more chip pockets. In some examples, other machines may be used in lieu of the stamping machine to punch the chip into the one or more chip pockets.

At block 460, the chip may include MasterCard or Visa information. At this point, no other information exists within the chip, such as card information or to whom the card is assigned to. The card may be associated with one or more card identifiers. In some examples, the one or more card identifiers may be printed adjacent to a corner of the card; however, other regions of the card may be used for display of the one or more card identifiers.

At block 470, the card may be sent to a vault or facility, such as a personalization facility, and the card is ready for pick up. One or more machines within the vault or facility may request the card based on the one or more card identifiers. The one or more machines may receive the card based on the one or more card identifiers and may perform encoding of the magnetic stripe; printing of data, such as account number information and user information, including first and last name, on the front and/or back of the card; encoding of the chip. For example, the card may comprise identification information displayed on the front and/or back of the card, and a contact pad. In some examples, the identification information may comprise one or more of cardholder name and expiration date of the card. The card may also include a magnetic stripe or tape, which may be located on the back of the card.

FIG. 5 illustrates a schematic of one or more layers of the card 500. FIG. 5 may reference the same or similar components of FIGS. 1-4 as explained above.

Card 500 may comprise one or more layers that are laminated together. Although single instances of each layer are depicted in FIG. 5, card 500 may include one or more layers for each layer. In some examples, the card 500 may comprise a first layer 510, such as an outermost or exterior layer which includes a layer that receives paint, ink, or laser treatment. The outermost or exterior layer may comprise the ceiling or top layer of the one or more laminated layers. The outermost or exterior layer may comprise a thin film that receives laser personalization. In some examples, the laser personalization may comprise custom laser personalization.
